Energy aware MAC protocol with mobility management in wireless body area network

In recent era, the area of monitoring the health of the patients is gaining an interesting research due to its notable properties in the smart health environment. For such application the biomedical sensors are equipped to gather the condition of the patient. Traditional methods in the same concern do not offer appropriate medical services to the user. During each emergency data transmission, there is less delay, increased energy consumption and reduced throughput. Further, the critical packets are not routed with higher priority. In some emergency conditions the data must be routed to the medical server (MS) with priority and thus avoid delay of medical services offered to the user/patient. Here, we propose QoS Effective Protocol (QoSEP) provisioned Wireless Body Area Network system for the effective routing of the critical packets to the destination MS. To improve the quality in service offered, we use Ant Colony Optimization for Critical Packet Routing for finding the shortest route with less energy consumption, low delay and high throughput. Here, the assumption of priority to the critical packets and scheduling is performed to improve the speed in emergency packet transmission. Finally, we evaluate the efficiency of the proposed method by comparison with other existing approaches. The achievements of the proposed QoSEP is compared in terms of energy consumption, throughput, PDR and delay. The performance of the proposed method is compared with the other existing methods and the performance of QoSEP is better than the other approaches. The simulation results achieve 97.5, 90 and 91% of throughput, 0.2, 0.05 and 0.3 J of energy, 0.1, 1, and 1.1 ms delay and 95, 91, 90% of Packet Delivery Ratio (PDR) for 10, 15 and 20 Access points respectively.
